The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2022:1287 advisory.

  - <code>NSSToken</code> objects were referenced via direct points, and could have been accessed in an unsafe     way on different threads, leading to a use-after-free and potentially exploitable crash. This     vulnerability affects Thunderbird < 91.8, Firefox < 99, and Firefox ESR < 91.8. (CVE-2022-1097)

  - After a VR Process is destroyed, a reference to it may have been retained and used, leading to a use-     after-free and potentially exploitable crash. This vulnerability affects Thunderbird < 91.8 and Firefox     ESR < 91.8. (CVE-2022-1196)

  - regex is an implementation of regular expressions for the Rust language. The regex crate features built-in     mitigations to prevent denial of service attacks caused by untrusted regexes, or untrusted input matched     by trusted regexes. Those (tunable) mitigations already provide sane defaults to prevent attacks. This     guarantee is documented and it's considered part of the crate's API. Unfortunately a bug was discovered in     the mitigations designed to prevent untrusted regexes to take an arbitrary amount of time during parsing,     and it's possible to craft regexes that bypass such mitigations. This makes it possible to perform denial     of service attacks by sending specially crafted regexes to services accepting user-controlled, untrusted     regexes. All versions of the regex crate before or equal to 1.5.4 are affected by this issue. The fix is     include starting from regex 1.5.5. All users accepting user-controlled regexes are recommended to upgrade     immediately to the latest version of the regex crate. Unfortunately there is no fixed set of problematic     regexes, as there are practically infinite regexes that could be crafted to exploit this vulnerability.
    Because of this, it us not recommend to deny known problematic regexes. (CVE-2022-24713)

  - If a compromised content process sent an unexpected number of WebAuthN Extensions in a Register command to     the parent process, an out of bounds write would have occurred leading to memory corruption and a     potentially exploitable crash. This vulnerability affects Thunderbird < 91.8, Firefox < 99, and Firefox     ESR < 91.8. (CVE-2022-28281)

  - By using a link with <code>rel=localization</code> a use-after-free could have been triggered by     destroying an object during JavaScript execution and then referencing the object through a freed pointer,     leading to a potential exploitable crash. This vulnerability affects Thunderbird < 91.8, Firefox < 99, and     Firefox ESR < 91.8. (CVE-2022-28282)

  - When generating the assembly code for <code>MLoadTypedArrayElementHole</code>, an incorrect AliasSet was     used. In conjunction with another vulnerability this could have been used for an out of bounds memory     read. This vulnerability affects Thunderbird < 91.8, Firefox < 99, and Firefox ESR < 91.8.
    (CVE-2022-28285)

  - Due to a layout change, iframe contents could have been rendered outside of its border. This could have     led to user confusion or spoofing attacks. This vulnerability affects Thunderbird < 91.8, Firefox < 99,     and Firefox ESR < 91.8. (CVE-2022-28286)

  - Mozilla developers and community members Nika Layzell, Andrew McCreight, Gabriele Svelto, and the Mozilla     Fuzzing Team reported memory safety bugs present in Thunderbird 91.7. Some of these bugs showed evidence     of memory corruption and we presume that with enough effort some of these could have been exploited to run     arbitrary code. This vulnerability affects Thunderbird < 91.8, Firefox < 99, and Firefox ESR < 91.8.
    (CVE-2022-28289)
